I have a LI account, but I don't use it effectively, so I can't speak from personal experience (which speaks to your point) But I do believe businesses like Angstro could build a valuable business off LI (they could build it off FB too, but the value is much less obvious). This is, of course, an in theory statement, not an in practice one. Presumably LI could add Angstro like features themselves? http://www.techcrunch50.com/2008/conference/presenter.php?presenter=49 http://www.techcrunch50.com/2008/conference/presenter.php?pr...
